Correct Answer: transponder

Solution : The correct option is a transponder.

The transponder is the name for the component located on communication satellites that receive, amplify, and retransmit signals from earth stations. Transponders refer to the channels of a communications satellite since each one has its transceiver or repeater. Multiple video and audio channels may pass via a single transponder on a single wideband carrier thanks to digital video data compression and multiplexing.
